TO ALL WHOMIT MAY CONCERN:

Beit kno-wn that I, PETER A. VOGT, of the city of Buffalo, in the county of Erie, and State ofNcw York, have invented a certain new and useful improvement in Refrigerators; and I do hereby declare that the following isa full and exact description thereof, reference being hadto the accompanying drawings, making part of' this specification, in which- Figure l is a cross vertical section in plane of line n: a', fig. 2.

Figure 2, a longitudinal vertical section in plane of line yy, iig. l.

Like letters designate corresponding parts in both figures.

My invention consists in the arrangement of a frigoriic air-chamber beneath the ice-box, in combination with the ydrip pipe, through which external air is admitted into said chamber, where it is cooled before entering the food-eompartment without coming in contact with the ice.

In the drawings, A represents the ice-box of a refrigerator, the ice resting on the ordinary bars b b. C is a top plate of the nir-chamber D, the plate C being made dishing, and inclined backward, (as shown,) to catch and conduct the drippings from the ice-box backward to the opening e, whence it falls and escapes through the drip pipe F, which descends from the back and lower portion of the air-chamber through the bottom of the refrigerator. The chamber D is provided with openings g g at the front and sides, for the escape of the air into the food-compartment I-I. I represents the door to the ice-box, for which I have heretofore obtained Letters Patent. The air from the'outside enters the refrigerator through the drip pipe directly into the chamber D, where it circulates, coming in Contact with the under surface of the plate C, which is kept constantly cool by the drippings on its upper surface. This reduces its temperature to the proper point, when it escapes through the apertures r/ into the food-chamber, where its greater gravity on account of its low temperature causes it to descend to the bottom of the refrigerator, whence it gradually rises as its temperature becomes elevated till it escapes through the aperture z' at the top, as shown by the arrows.

By the use of my improvement a great saving in ice is effected, as the air by not coming in contact therewith does not melt it, as in ordinary refrigerators, where the warm air is brought in immediate connection with and circulates among the pieces, melting them very rapidly. It also prevents the possibility of the drippings from the ice falling upon the articles in the compartment beneath.

Another important advantage is, that the air by being cooled by the dry under surface of the plate G in chamber D, instead of by the surface of the ice itself, remains comparatively dry, which greatly increases its preservative qualities; whereas, in the other case, it becomes heavily charged with moisture from its intimate contact with the ice, and from the rapid evaporation that is constantly taking place.

In refrigerators constructed with a simple eXtra -bottom beneath the ice-chest for catching the drippings from ice above, great inconvenience is experienced from the condensation of vapor on the under surface of this bottom, owing to its low temperature, which collects and drips upon the articles beneath. By the employment of the chamber D this condensed moisture in falling is intercepted by the bottom s of the' latter, and oonducted to the' mouth ofthe drip pipe, while the circulation of the air in the chamber prevents the temperature of tho bottom s falling below that of the air, and consequently no condensation can take place on its under surface. lhc protection which this affords is an advantage of the greatest importance. l

What I claim as my invention, is

The refrigerating air-chamber D, provided with eduction apertures g g, when so arranged under the icc-box, and combined with the drip and induction air pipe F and final escape passage z', that theair entering the refrigerator will pass dircctlyinto t-he said air-chamber throughthe drip pipe and thence into the food-compartment without coming incontact with the ice, substantially in the manner and for the purposes set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.v

PETER A. VOG'I.
